I have a different procedure: if someone criticises me, I quietly consider if what they have said is true* if it isn't then I ignore the comment and put it down to the inevitable misunderstandings of a cluttered environment. If it is true, then I think what I should do about it to become a better person, pilot, partner, whatever. Thus through interaction one progresses.
*this step can involve a delay, to be perfectly honest.
Agreed with respect to true statements.

However, in this case, the statement is not true, imho, and having been repeated multiple times and reinforced by many others, deserves a response. My response is to learn to be a good fighter pilot and shoot down offending pilots with substantial frequency and emphasis on the concept of pwnage. Hopefully said pilots will learn that the mighty Spitfire is an awesome aeroplane to behold and to respect when one approaches.

Hopefully said offending pilots, especially those with significant skill, will also see there are no training wheels attached to the Spitfire as it gets really close just before the cannons fire.

To ignore falsities as "inevitable misunderstandings" is a cop-out and instead require a more deserving response.
